There's a section [1] on the page that has instructions, and video [2] too. I had to select the English (US) language to get the option to select ClearFlow.

Thanks. It's available only for the US layout, not UK.
I'm writing down a few impressions: - the layout is unusual, but I get the motivation. Distances are minimised and letters are arranged so that ambiguity is removed. - although I'm very slow, I haven't made a single mistake so far. Clearflow allows me to swipe much more accurately than stock gboard. - the square keyboard layout unfortunately means that half the letters are constantly hidden behind my thumb. As I'm unfamiliar with the layout, this means that before swiping a word, I have to look at the layout, memorise letter locations and plan the movement - since I write in multiple languages and Clearflow is available in only one of them, I would have to memorise a completely new layout for a language I write in only half the time.
Hi, Yes I'm in the same boat as you - had to switch to US language instead of UK. I've been addiing the anglisised versions of words to my dictionary as I go along so it's becoming less of an issue over time. Maybe I'll switch to FUTO in order to not have to deal with this anymore. Gboard has one nice feature though in that I have multiple languages enabled so I get correct predictive completion in non-English languages.
For learning ClearFlow, I used the Games app available from the "Clearflow Games" section on their website: https://clearflowkeyboard.github.io/
I also have the issue of the thumb getting in the way so I spent a couple of days playing the games to get my layout memory up and then it became usable without frustration and I'm not looking back now although I occasionally still forget the odd letter location.
FUTO has a "multilingual typing" setting, maybe that's what you're looking for?
